Introduction
Are you willing to follow Jesus even when His mission collides with your comfort, your preferences, and even your closest relationships? Here is the central truth I want you to grasp and live: Jesus came to bring God’s purifying fire, judgment and salvation through the cross, and if I follow Him, I must receive both the Holy Spirit and the refining fire that reshapes my whole life.
We are walking through Luke’s Gospel not by picking only the “highlight reel,” but by listening carefully to some of Jesus’ hardest teachings. That matters in a post-Christian world where many people have reference points to Jesus but not clarity about His mission. If you asked people on the street, “Why did Jesus come into the world?” you might hear: “He’s one of many spiritual teachers,” or “He helps people feel better,” or “He came to awaken love and inner peace.” Even some who respect Jesus will say, “I don’t like church or the Bible, but I love His teachings because they’re about love and acceptance.”
There’s truth in some of that, but it’s not the full picture. If you really want to know Jesus, you must listen to Jesus. And in Luke 12:49–53, He tells us something many people never include in their version of Him. > “I came to send fire on the earth… Do you suppose that I came to give peace on earth? I tell you, not at all, but rather division…” (Luke 12:49–53)

Jesus Brings Purifying And Judging Fire
Jesus says, “I came to send fire on the earth,” and He does not say it apologetically. He even adds, “how I wish it were already kindled” (Luke 12:49). That should correct the image of Jesus as a therapist, a life coach, or a harmless moral guide we can keep at arm’s length. He came to do something decisive in the world.
This “fire” is not random destruction; it is the Bible’s longstanding image of God’s purification and judgment against sin, spoken in the language of the Old Testament prophets.
- Nahum 1:6 asks, “Who can stand before His indignation?” and describes God’s fury “poured out like fire.”
- Malachi 4:1 pictures the day of the Lord “burning like an oven,” where the proud and wicked become “stubble.”
I need you to understand this: God hates evil. And because you are made in God’s image, you also hate evil. This is why our culture still cries out for justice. When we hear about sex trafficking, child abuse, murder, something inside us says, “That must be punished.” We long for a world where wrong is dealt with, not excused.
But here’s what makes judgment uncomfortable: deep down we know we are not only observers of evil, we are also participants in sin. If God judges evil, what about me? What about you? Until you face that honestly, you won’t understand why Jesus came.
Jesus Bears The Fire Through The Cross
Immediately after saying He brings fire, Jesus says:
“But I have a baptism to be baptized with, and how distressed I am till it is accomplished.” (Luke 12:50)
He is not referring to His water baptism at the start of His ministry. He is speaking about the baptism of suffering and death, the cross. We see this same meaning when Jesus told His disciples they didn’t understand what they were asking when they wanted positions of honor:
“Are you able… to be baptized with the baptism that I am baptized with?” (implied from the Gospel accounts; see Mark 10:38)
And we hear it again in John’s Gospel as Jesus approaches the cross:
“My soul is troubled… but for this purpose I came to this hour.” (John 12:27)
John the Baptist summarizes Jesus’ mission with crystal clarity:
“Behold! The Lamb of God who takes away the sin of the world!” (John 1:29)
This is Passover language: a sacrifice given so that judgment passes over God’s people. The gospel is incredible news, but only because it addresses alarming news: sin must be judged, and Jesus came to take that judgment.
That’s why the cross is not an accident of history; it is the center of His mission. And that’s why Jesus can say “It is finished” (John 19:30). On this side of the cross, we live under grace because He truly absorbed what we could not.
Romans puts it like this:
“God demonstrates His own love toward us, in that while we were still sinners, Christ died for us… we shall be saved from wrath through Him.” (Romans 5:8–9)
So yes, Jesus brings fire. And yes, Jesus is love. The love is not sentimental; it is costly. He loves us by taking the judgment we deserved.
The Cross Defines The Call To Discipleship
Once you understand the cross, you can understand the call. A “cross-less Jesus” produces a “cross-less Christianity,” where faith becomes a strategy for personal comfort and the “best life now.” But Jesus doesn’t invite us into that illusion.
When His disciples insisted, “We are able,” Jesus did not correct them by saying suffering would never touch them. He said, in effect, that they would indeed share in His cup and baptism (again, implied from the Gospel accounts like Mark 10:39). In other words: His path shapes our path.
So I want to speak plainly as I disciple you: Jesus gives eternal life, and He also gives you an earthly cross. If you expect Jesus to exist mainly to meet your desired outcomes, you will misunderstand Him and eventually stumble over Him. But if you see Him clearly, you will learn to trust God not only in blessing, but through suffering, and even through death, because you’re living for the reward beyond this life.
Baptized With The Spirit And Fire
John the Baptist said:
“He will baptize you with the Holy Spirit and fire.” (Luke 3:16)
Notice the twofold mission: Holy Spirit and fire. Many people want only one side.
- One extreme says: “Come as you are, stay as you are.” Grace gets turned into permission to remain unchanged.
- Another extreme turns refinement into mere moralism, forgetting adoption and new birth.
But Jesus does both. You are received by grace, like an orphan being adopted. You don’t earn adoption; you come needy and are welcomed. Yet the Father does not adopt you to leave you in bondage. He adopts you to transform you.
I want you to picture gold: when it’s found, it’s precious as it is, worth retrieving immediately. But it doesn’t become jewelry until it’s refined, until the dross is removed. This is what God does in you. He calls you precious, and then He purifies you because He loves you.
Peter describes this discipleship reality:
Trials come “that the genuineness of your faith, being much more precious than gold… though it is tested by fire… may be found to praise, honor, and glory at the revelation of Jesus Christ.” (1 Peter 1:6–7)
So when you experience “various trials,” don’t assume God has abandoned you. Learn to see suffering, pressure, and testing as the Refiner’s work, painful, yes, but purposeful.
Peace With God, Division In The World
Then Jesus says something that sounds shocking:
“Do you suppose that I came to give peace on earth? I tell you, not at all, but rather division…” (Luke 12:51)
How can that be, when we sing about “peace on earth”? Here’s the key: Jesus brings peace with God, real reconciliation between God and sinners. But that peace will cost you your attachments to the world, and sometimes it will even strain your closest relationships.
Jesus gets very specific: households divided, father against son, mother against daughter, and so on (Luke 12:52–53). In Matthew’s parallel teaching He says He came to bring “a sword” (Matthew 10:34), not a sword of violence, but a blade of separation: allegiance to Jesus will expose competing allegiances.
This is not unique to Christianity. Any deep devotion creates boundaries: when you say “yes” to something ultimate, you necessarily say “no” to other claims. But Jesus is saying the stakes are ultimate, and therefore the cost can be heartbreaking.
Some of you know this personally. Following Jesus has meant leaving behind the religion of your upbringing, or breaking with a family tradition, or losing approval you once depended on. Some of you came to Christ while entangled in a messy worldly relationship and had to speak hard truth, draw new lines, and accept the fallout. This is part of the refining. Jesus does not hide it from you, He loves you enough to tell you the truth upfront.
Conclusion
So why did Jesus enter the world? He tells you: He came to bring fire, God’s purifying judgment against sin. And He also came to undergo a baptism of suffering, the cross, so that judgment would fall on Him instead of you. That is why the cross is not a footnote; it is the mission.
And now the question becomes personal: why did Jesus come into your world right now? To give you life by the Holy Spirit and to refine you by fire, until your faith becomes pure, your loves become ordered, and your allegiance becomes unmistakably His.
Don’t settle for a Jesus you can use. Receive the real Jesus who saves you from wrath, reconciles you to God, and then calls you to take up your cross and follow, whatever it costs.
Father, thank You for sending Jesus into the world not only to teach us, but to save us. Help me to see clearly that You are holy, that sin is real, and that Your judgment is just. Thank You that Jesus took upon Himself the baptism of suffering and the wrath my sin deserved, and that by His blood I can be justified and saved.
Lord Jesus, I surrender my false expectations and my desire for comfort without change. Baptize me afresh with the Holy Spirit and with fire. Refine my heart like gold. Teach me to trust You in trials, to carry my cross, and to follow You with courage.
And Father, where my devotion to Christ brings division or tension in relationships, give me humility, gentleness, and steadfast love, without compromise. Make my life faithful, purified, and full of Your peace with You. In Jesus’ name, amen.
